IMPROVEMENT IN MOTORS.

Specification forming part of Letters Patent No. 180.786, dated August8, 1876; application filed J une 2, 1876.

, power for running pumps or other machinery,

as will be hereinafter more fully set forth.

In the annexed drawing, which fully illustrates my invention, Arepresents a suitable frame, inwhich the working parts are arranged. Bisa drum, secured upon a shaft, a, and provided with pins b,-which projectradial] y at equal distances apart from the periphcry of the-drum. Thesepins catch in the links of a chain, 0, which passes over the drum, andhas a weight suspended at one end,

. by means of which the power is driven. At

the side of the drum B is a large cog-Wheel, D, secured either to thedrum or shaft, and meshing with a pinion, 01, secured upon anothershaft, 0, and this shaft is at one end provided with a crank, E, forwinding up the power. On the shaft a is further secured a ratchet-wheel,Gr, and on the side thereof is placed a cog-wheel, H, loosely on theshaft, and said cog-wheel provided with a springpawl, f, to take intothe ratchet-wheel G, and the cog-wheel H thus be turned with it whenrotatingin the proper direction, while in winding up the power theratchet-wheel slips by the pawl. The large cog-wheel H is, by means of aseries of pinions, i, and wheels h, secured upon suitable shafts, likeany ordinary train of gearing, connected with a pinion, it, upon ashaft, k, which at one end carries the flywheel I. This shaft 70 hasanother pinion, m, which meshes with and rotates a large cogwheel, J,secured upon a shaft, p. Upon the front end of the shaft 17 is secured alarge bevelcog wheel, L, whichmeshes with a bevel-pinion, S, upon avertical shaft, M, having its bearings in suitable arm's projecting fromthe front of the frame A. On the upper end of the shaft M is fastened ahead, N, slotted on opposite sides, and provided in said slots withpivoted governor arms 0 0, having balls or weights upon their outerends. On the shaft M, below the wheel L, is further secured a cam-wheel,P, constructed as shown in the drawing-that is to say, it has a seriesof corrugations, w a, around the rim on the under side. On the lowerbearing-arm for the shaft M is pivoted a walking-beam, R, which is bentangularly in the center, so that its two ends or arms will be in thesame vertical plane as the center of the shaft. On this beam, on eachside of the shaft, are projections, in which are mountedfriction-rollers t t, having their axes running longitudinally with thearms of the walking-beam. When the machine is in motion the cam Poperates alternately upon these rollers, giving the beam the requiredrocking motion.

On each end of the walkingbeam R is placed an adjustable weight, S,fastened at any point desired by a set-screw, w, to give thewalking-beam the proper balance when connected to a pump or othermachinery to be driven.

The power is wound up as described, and will then run and operate themachinery to which it is connected for as long a time as the length ofthe chain will admit.

The fly-wheel I keeps up the momentum of the power, and the governor N Oon the shaft M causes it to run with a steady and uniform motion.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

In a power operated by a weighted chain, the combination of the verticalshaft M, with head N and governor-arms O O at its upper end, thecam-wheel P, formed with the corrugations x a and secured on said shaft,and the walking-beam R, with friction-rollers t t, substantially as andfor the purposes herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this20th day of May, 1876.
